Comment(by jon.nettleton):

 Just wanted to update that this comparison isn't really valid, as the XO1
 is running a color depth of 16bpp and the XO 1.5 is a bit depth of 24bpp.
 Considering the increase in bit depth and the relatively small loss in
 performance, I say small because the number of full screen fills is
 greater than the vrefresh, I don't think this is a performance degradation
 any longer.  If you would like a performance comparison here are the
 numbers of test2.py run under 16bpp

 Test #0, n=80, elapsed=0.72, fps=110.59
 Test #1, n=80, elapsed=0.70, fps=113.72
 Test #2, n=80, elapsed=0.70, fps=113.97
 Test #3, n=80, elapsed=0.70, fps=114.07
 Test #4, n=80, elapsed=0.70, fps=113.77

 The pulseaudio problem could be various things. Make sure you don't have a
 custom asound.conf.  Remove the ~/.pulse* so alsa doesn't try and connect.
 check rpm -qa '*pulse*' you should only have pulseaudio-libs-glib2 and
 pulseaudio-libs.  There may be some other places where ALSA may link into
 pulse.  If you still have problems open  that as a separate ticket.
